Understanding the problem

We need to administer 150 mL of the medication over 30 minutes.

We need to determine the flow rate in mL/hr.

Step-by-step calculation

Convert minutes to hours:

30 minutes = 0.5 hours

Calculate the flow rate:

Flow rate (mL/hr) = Total volume (mL) / Infusion time (hours) = 150 mL / 0.5 hours = 300 mL/hr

Therefore, the nurse should set the IV pump to deliver 300 mL/hr.

Step-by-step solution:

1. Calculate the total daily dose:

Total daily dose = dose per kg/day x weight in kg = 3 mg/kg/day x 50 kg = 150 mg/day

2. Calculate the dose per administration:

Since the medication is divided into 3 doses per day,

Dose per administration = Total daily dose / number of doses = 150 mg/day / 3 doses = 50 mg/dose

3. Calculate the volume to administer:

The medication concentration is 40 mg/mL.

Volume = Dose per administration / Concentration = 50 mg / 40 mg/mL = 1.25 mL

4. Round to the nearest tenth:

Volume = 1.3 mL

Therefore, the nurse should administer 1.3 mL of tobramycin per dose

1. Convert ounces to milliliters (mL):

• 1 ounce (oz) is approximately equal to 30 mL.

• Orange juice: 12 oz * 30 mL/oz = 360 mL

• Ice chips: 12 oz * 30 mL/oz = 360 mL (Note: Ice melts to about half its volume, so we'll divide this by 2 later)

• Coffee: 6 oz * 30 mL/oz = 180 mL

• Skim milk: 4 oz * 30 mL/oz = 120 mL

• Water: 24 oz * 30 mL/oz = 720 mL

1. Account for ice chips melting:

• Ice chips: 360 mL / 2 = 180 mL

1. Add up all the fluid intake in mL:

• Orange juice: 360 mL
• Ice chips: 180 mL
• Coffee: 180 mL
• Skim milk: 120 mL
• Water: 720 mL
• IV fluid: 1000 mL

Total: 360 + 180 + 180 + 120 + 720 + 1000 = 2560 mL

Understanding the problem

We need to administer 4000 mcg of Rosuvastatin.

The available tablets are 2 mg each.

We need to determine the number of tablets to administer.

Step-by-step calculation

Convert mcg to mg:

1 mg = 1000 mcg

4000 mcg = 4 mg

Calculate the number of tablets:

Number of tablets = Desired dose (mg) / Tablet strength (mg) = 4 mg / 2 mg/tablet = 2 tablets

Therefore, the nurse should administer 2 tablets of Rosuvastatin.

Step-by-step solution:

1. Convert pounds to kilograms:

1 lb = 0.453592 kg

33 lb x 0.453592 kg/lb = 14.97 kg

2. Calculate the total daily dose of digoxin:

Total daily dose = dose per kg/day x weight in kg = 8 mcg/kg/day x 14.97 kg = 119.76 mcg/day

3. Calculate the dose per administration:

Since the medication is divided into 2 doses per day,

Dose per administration = Total daily dose / number of doses = 119.76 mcg/day / 2 doses = 59.88 mcg/dose

4. Convert mcg to mg:

1 mg = 1000 mcg

59.88 mcg = 0.05988 mg

5. Calculate the volume to administer:

The medication concentration is 0.05 mg/mL.

Volume = Dose per administration / Concentration = 0.05988 mg / 0.05 mg/mL = 1.1976 mL

6. Round to the nearest tenth:

Volume = 1.2 mL

Therefore, the nurse should administer 1.2 mL of digoxin per dose.

We need to administer 475 mg of daptomycin.

The reconstituted solution has a concentration of 0.5 g/10 mL, which is equivalent to 50 mg/mL.

Calculation:

Volume (mL) = Desired dose (mg) / Concentration (mg/mL) = 475 mg / 50 mg/mL = 9.5 mL

Therefore, the nurse should administer 9.5 mL of the reconstituted daptomycin solution.

Understanding the problem

We need to administer 2g of nafcillin.

The reconstituted solution has a concentration of 250 mg/mL.

We need to determine the volume to administer.

Step-by-step calculation

Convert grams to milligrams:

2 g = 2000 mg

Use the formula:

Volume (mL) = Desired dose (mg) / Concentration (mg/mL) = 2000 mg / 250 mg/mL

Calculate the volume:

Volume (mL) = 8 mL

Therefore, the nurse should administer 8 mL of the reconstituted nafcillin solution.

A. Enoxaparin 30 mg subcutaneous every 12 hours:

Enoxaparin is correctly prescribed at 30 mg every 12 hours for conditions like deep vein thrombosis. This dosing regimen is standard and does not require clarification.

B. Hydrochlorothiazide 50 mg PO twice daily with meals:

Hydrochlorothiazide is typically administered once daily, but doses up to 50 mg twice daily can be appropriate for specific conditions. This prescription is higher than usual but still within potential therapeutic ranges, so clarification is not immediately necessary unless there are other concerns.

C. Lovastatin 20 mg PO once daily:

Lovastatin at 20 mg once daily is a common dose for managing hyperlipidemia. This dosage is standard and does not require clarification.

D. Diltiazem 30 mg PO hold for apical pulse rate less than 50/min:

Diltiazem is a calcium channel blocker often used to manage hypertension or angina. The dose of 30 mg is quite low for this medication, and the instruction to hold if the apical pulse rate is below 50/min is standard. However, the very low dose of 30 mg might be unusual and needs clarification to ensure it is appropriate for the patient's condition and to prevent potential adverse effects.

A. Aspirin 81 mg PO daily:

Aspirin 81 mg daily is commonly used as a low-dose regimen for cardiovascular protection or as a preventive measure for certain conditions. This dosage is standard and does not require clarification.

B. Acetaminophen 1000 mg PO every 6 hours prn for mild-moderate pain:

The maximum recommended dose of acetaminophen is generally 4000 mg per day. A dose of 1000 mg every 6 hours, which totals up to 4000 mg daily, is within the acceptable limit for managing mild to moderate pain, assuming no liver dysfunction is present. This prescription is appropriate and does not need further clarification.

C. Ibuprofen 400 mg PO every 4 hours prn for mild-moderate pain:

Ibuprofen is typically dosed at 200 mg to 400 mg every 4 to 6 hours as needed. A dose of 400 mg every 4 hours is within the usual range for managing mild to moderate pain, and the total daily dosage should be monitored to avoid exceeding recommended limits. This prescription is generally acceptable.

D. Amoxicillin 250 mg tablet PO X7 days:

Amoxicillin is usually prescribed at higher doses for infections. A common dosage is 500 mg to 875 mg every 8 hours, depending on the infection being treated. The prescription of 250 mg for 7 days is unusually low and might not be effective for most infections, requiring clarification to ensure appropriate antibiotic therapy.
